What is an IP address?
On the internet every device has it’s own Internet Protocol (IP) address. An IP address consists of 4 numbers seperated by periods: as example, your IP address might look like something like this ‘22.214.171.124’. If a computer has an IP address, all the computers on the internet can easily find that computer. Meaning if you know the IP address of a website you can connect there by typing the address to your web scanner. But since it’s quite hard to keep these numbers in mind, every IP address has been named with a domain name. A network made of special server computers provided by your internet service provider, keeps the data of which IP address belongs to which domain name and orientates the users to the right addresses. Internet traffic being stable relies on these IP addresses. So that there is no mess.
You too, when you connect to the internet, get an IP address attached to your computer. However, many of the users have dynamic IP addresses, meaning that you’ll be given an IP address that is free to use in your internet service provider at the time. That’s why the last number of your IP address changes everytime you connect.
Some of the IP addresses are static, meaning that they never change. Internet service providers have recently started giving static IP service to their ADSL users.
IPv4 will soon run out of IP’s. The reason to this is that most of the IP’s are taken by providers.
IP’s are actually addresses translated from machine language. An upper version of these addresses are domain names.
